Network ups Tool - keeps going stale and d/c

Third party integrations

This is a recent problem since updating to HA 2021.3.4. Network UPS tool add on suddenly and randomly disconnects and won’t reconnect unless I manually hit “restart”. This seems to happen every 10-15 hours or so.

The log is 100+ lines of:

5230.394315 Poll UPS [CyberPower1500@localhost] failed - Data stale
35235.395255 Poll UPS [CyberPower1500@localhost] failed - Data stale

What does that mean? And why doesn’t it auto restart on failure as it’s supposed to?

HA and the NUT addon are separate, the issue should not (but still maybe is) caused by the HA update, I am also using HA 2021.3.4 and NUT and have 0 issues, but I am not using an addon.

What is the version of the NUT addon?

im currently using 0.6.2 Nut version.

Any idea what it means by “stale”? Maybe if i can get some info on that error i can narrow down what’s causing it; or come up with a workaround to fix it
